MACHINE FOR FORMING CARD-CYLINDERS.

To all whom it may concern Be it known that I, EDWARD GoLsToN LOVELL, a subject of the King of Great Britain, residing in Bristol, England, have invented certain new and useful Improvements in Machines for Forming Card-Cylinders, of which the following is a specification.

This invention relates to improvements in and relating to machines for forming cardboard cylinders, and it refers to machines of the kind in which the cylinder is formed by coiling the cardboard, suitably coated with adhesive, around a mandrel from which it is afterward stripped by any suitable means.

The present invention has for its object certain improvements in machines of this class whereby it is readily possible to produce tubular cardboard bodies of square, oval, or any other desired cross sectional outline without interfering with the main portion of the machine.

Now according to the present invention I take the cylinders as they are removed from the mandrel upon which they are made and pass them through a hollow former which at one end is of circular cross section, and at the other is of such outline as it is desired shall be imparted to the cylinders. The former is perforated at certain points of its length and at the perforations I provide rollers which act in conjunction with the former and the peripheries of which rollers are suitably curved or shaped for this purpose.

In order that the invention may be the better understood drawings are appended in which Figure 1. is a side elevation of a former having the perforations and rollers omitted. Fig. 2. a front end view thereof. Fig. 3. is a rear end view. Fig. 4:. is a side elevation showing the rollers in place Fig. 5. is a side elevation showing the former without the rollers applied to an existing machine.

Referring to the accompanying drawings a indicates the body of the former which at the entrant end is preferably slightly flared or bell mouthed as shown at a to facilitate the entry of the card cylinder. The former at the entrant end is of circular cross sectional form and such outline, starting from the front end, or at some other convenient point of its length, gradually changes its cross ectional outline until at the exit end a it corresponds to the cross sectional out- Specification of Letters Patent.

line it is desired the cylinder shall present. As previously stated I may first discharge the cylinder from the mandrel upon which it is made into a tubular receiver in which it remains until the succeeding cylinder pushes it out and into the former which is arranged in line with said receiver. In practice, however, I find it convenient to discharge the cylinder straight into the former.

In Fig. 5. the invention is illustrated as applied to the machine forming the subject of U. S. Letters Patent No. 1056191, and in this case the former a is disposed at the end of the mandrel b so that as the body 0 is moved lengthwise upon the mandrel the cylinder is pushed 01f directly into the former a.

As shown in Fig. 4c, pairs of rollers such as (Z 6 f are. provided, mounted on suitable spindles, not shown, and arranged upon each side of the former, the body of which is provided with perforations cl, 6, f at these respective points to permit the rollers to come into contact with the exterior surface of the cylinder. Instead of only two such rollers four may be employed so that the whole or substantially the whole of the perimeter of the cylinder is acted upon. The rollers may be operated by contact with the cylinder or they may be positively driven. I may, if desired, construct the former in two parts hinged together, the parts being separated to permit the passage of the cylinder therein and then closed to compress same and give it the desired outline. Under these circumstances the shape of the former would be the same from end to end. As the adhesive connecting the convolutions of the material forming the cylinder is not set or hard at the time of treatment the said cylinder may be readily caused to assume any desired cross outline, and I am, therefore, enabled, by means of my invention, to readily impart to the cylinders any desired cross sectional outline without requiring the shape of the mandrel or any other detail of the main machine to be altered or interfered with. Obviously the former may be of any desired length so that the cylinders may be retained thereon for a longer or shorter period as may be found desirable to secure their proper formation.
